Why are such different animals as fishes amphibians reptiles birds and mammals grouped in to a single phylum?

These animals are all grouped under a single phylum because they all have a vertebrae, or spinal column. They belong to the phylum Chordata taken from the latin chordate.

∙ 12y agoTaxonimic levels such as Phylum, and Order, group organisms together by shared characteristics. As you go down the taxonomic levels, the organisms are split up further and further, due to differences between each other that require them to be classified seperately.
'Animalia' is one of the Kingdoms. All animals belong to it, because the criteria for inclusion here is that the organism is an animal. Phylum is the first division amonst the Kingdom, there are about 40 of them, one is 'Chordata', animals with a spinal cord. All fish, amphibians, reptiles, birds and mammals, have this. This is why they are grouped together in the phylum level, before being divided by Class, such as Mammalia, and Aves.

∙ 9y agoClassification is intended to approximate the evolutionary relationships of organisms. In other words, organisms that are closely related are grouped together. Because fish, mammals, reptiles, birds, and amphibians all have backbones, scientists know that they are evolutionarily related. About 530 million years ago, the first fish evolved. Eventually, a type of fish evolved the ability to spend time on land, leading to amphibians. Amphibians continued to evolve, leading to reptiles, which later evolved into mammals and birds. Hence, all these groups are related by evolution and should be grouped together.

What is the basis in grouping the animals?
All animals are different as per according to their size, structure and behaviour so, according to all these features they are grouped. Basically, they are classified into five groups such as Fishes, Birds, Amphibians, Reptiles and Mammals.
Are amphibians and reptiles and birds and mammals all in the same class?
No, not in a straight forward traditional classification sense... Amphibians = class Amphibia Reptiles = class Reptilia Bird = class Aves Mammals = class Mammalia They can be categorized all together in the "superclass" Tetrapoda.
Do all amphibians belong to the class reptilia?
No because the amphibian group is found in specific areas much different then the reptile. also the reptile has a different look and shape to its body!Amphibians have an almost slimy look to their bodies and must always live very very close to water. Reptiles have a rough texture to their bodies and can live in places like the desert and get along fine with very little water. Reptiles almost always have tails this is not true with amphibians. As you can see they are very different and should not be grouped together.
What is the group in which diploblastic animals found?
Diploblastic animals usually develop from the blastula. They were initially grouped in the phylum Coelenterate. They were then removed and grouped in a different phyla when the differences were discovered.
How many groups of animals?
There are approximately 1.5 million known animal species grouped into around 35 phyla, including mammals, birds, reptiles, amphibians, fish, and invertebrates. Each group exhibits unique characteristics and adaptations based on their evolutionary history and ecological niche.
Why is a frog and a lizard grouped in the same phylum?
No. Frogs are amphibians and fish are fish.
Why do reptiles get there classification?
The reptiles were from the outset of classification grouped with the amphibians. Linnaeus, working from specie's Sweden, where thecommon adder and grass snake are often found hunting in water, included all reptiles and amphibians in class "III -- Amphibious" in his System's Nature.[1] The terms "reptile" and "amphibian" were largely interchangeable, "reptile" (from Latin rep ere, "to creep") being preferred by the French.[2] Josephus Nickolaus Laurenti was the first to formally use the term "Reptilia" for an expanded selection of reptiles and amphibians basically similar to that of Linnaeus.[3] It is today stil common to treat the two groups under the same heading as herptiles.
Animals are often grouped as?
Animals grouped to together are called iplomas. Trust Me!
Amphibians are grouped in what kingdom?
Amphibians are part of the kingdom Animal. Same worms and humans. To narrow it down, they are part of the Phylum Chordate.
How are farm animals grouped?
They are grouped by species. Then by intellegence
How are animals characterized into phylums?
they are grouped.
Can animals and plants can be grouped by observing their diets?
Animals are more typically grouped by their diets than plants, for example, herbivores, omnivores, and carnivores.Plants may need different amounts of nutrients, but all need light, moisture, Nitrogen, Potassium, and Phosphorous.
